Displays the system hardware inventory of the ACE. This command displays information about the field replaceable units (FRUs) in the ACE, including product identifiers, serial numbers, and version identifiers. The raw option displays information about each temperature sensor (ACE module) or component (ACE appliance) in the ACE.

For descriptions of the fields in the show inventory command output, see the following table:

(ACE module only) Displays whether the master or the slave network processor console is directed to the base board front panel for the specified daughter card. For example, if the master network processor is directed to the front panel, the following message appears:

Displaying General System Process Information

To display general information about all of the processes running on the ACE, perform the following task:

Command

Purpose

show processes [cpu | log [details | pidprocess_id] | memory]

Displays general information about all of the processes running on the ACE. This command is available only to users with an Admin role across all contexts. The displayed system processes information is at the CPU system level (the total CPU usage) and is not on a per-context level.

The show processes command with no options displays summary CPU information for the SiByte 1250 Processor (ACE module) or Intel Pentium processor (ACE appliance). Table 6-5 describes the fields for the command output.

Displays the system information. The keywords and argument are as follows:

•cpuhog—Displays information related to the process watchdog timer that monitors CPU usage by any currently active processes. This keyword is intended for use by trained Cisco personnel for troubleshooting purposes only.

•error-id—Displays description about a specific error ID or all error IDs.

–hex_id—Error ID in hexadecimal format. The range is from 0x0 to 0xffffffff.

–list—Displays all error IDs.

•internal—Displays Cisco internal system-related functions. The internal keywords and options are intended for use by trained Cisco personnel for troubleshooting purposes only. This option is available in the Admin context only.

•skbtrack—Displays the socket buffer (network buffer) allocations in the kernel loadable modules. This keyword is intended for use by trained Cisco personnel for troubleshooting purposes only.

•uptime—Displays how long the ACE has been up and running, see Table 6-13. This keyword is available in all user contexts.

•watchdog [lcp | memory | scp]—Displays whether the watchdog is enabled or disabled. When it is enabled, its timeout is displayed. When you enter the watchdog keyword without an option, all watchdogs are displayed, see Table 6-14. To display a specific watchdog, enter one of the following options:

–lcp—(ACE module only) LCP process watchdog. The current SCP watchdog watches this process. However, if the LCP process is not scheduled on time, this watchdog reboots the ACE module.

RAM used for the page cache (disk cache) minus the RAM used for the swap cache.

SwapCached

Memory that once was swapped out, is swapped back in, but is still in the swap file. If this memory is needed, it does not need to be swapped out again because it is already in the swap file. This saves I/O.

Active

Memory that has been used recently and usually not reclaimed unless it is absolutely necessary.

Inactive

Memory that is unused or easily freeable.

HighTotal

Total amount of memory in the high memory (highmem) region. Highmem is all memory above approximately 860 MB of physical RAM. The kernel uses indirect methods to access the high memory region. Data cache can go in this memory region.

HighFree

Total amount of available memory in the highmem area.

LowTotal

Amount of memory in the low memory region (non-highmem memory).

LowFree

Amount of free memory in the low memory region. The kernel can address low memory directly. All kernel data structures need to go into low memory.

SwapTotal

Total amount of physical swap memory.

SwapFree

Available swap memory.

Committed_AS

An estimate of how much RAM you would need to make a 99.99% guarantee that there never is an out-of-memory (OOM) condition for a particular workload. Normally, the kernel overcommits memory. For example, if you dynamically allocate 1 GB of memory, no demand is placed on that memory until you actually start using it. The Committed_AS is an estimate of how much RAM or swap memory you would need in a worst-case scenario.

Table 6-12 Field Descriptions for the show system resources Command

Field

Description

Load average

Load that is defined as the number of running processes. The average reflects the system load over the past 1-minute, 5-minute, and 15-minute interval.

Processes

Number of processes in the system, and how many processes are actually running when you enter the command.

CPU states

CPU usage percentage in user mode, kernel mode, and idle time in the last second.

Memory usage

Total memory, used memory, free memory, memory used for buffers, and memory used for cache in KB. Buffers and cache are also included in the used memory statistics.

Table 6-13 Field Descriptions for the show system uptime Command

Field

Description

System start time

Date and time when the ACE was turned on

System uptime

Length of time that the ACE hardware and software have been running

Kernel uptime

Length of time that the operating system (OS) has been running

Table 6-14 describes the output fields for the show system watchdog command.

Table 6-14 Field Descriptions for the show system watchdog Command

Field

Description

LCP watchdog

(ACE module only) State of the LCP process watchdog: Enabled or Disabled.

Memory watchdog

State of the low memory watchdog: Enabled or Disabled.

SCP watchdog

(ACE module only) State of the SCP watchdog: Enabled or Disabled.

Timeout

Timeout interval for the enabled watchdog. When the watchdog is disabled, its timeout is not displayed.

Displaying or Clearing ICMP Statistics

To display or clear the Internet Control Message Protocol (ICMP) statistics, perform one of the following tasks:

Number of ICMP echo request messages transmitted or received by the ACE

Echo Reply

Number of ICMP echo reply messages transmitted or received by the ACE

Unreachable

Number of ICMP unreachable packets transmitted or received by the ACE

TTL Expired

Number of ICMP TTL-expired messages transmitted or received by the ACE

Redirect

Number of ICMP redirect messages transmitted or received by the ACE

Mask

Number of ICMP Address Mask Request messages transmitted or received by the ACE

Param problem

Number of ICMP Parameter Problem messages transmitted or received by the ACE

Source Quench

Number of ICMP Source Quench messages transmitted or received by the ACE

Time Stamp

Number of ICMP Time Stamp (request) messages transmitted or received by the ACE

Displaying or Collecting Technical Information for Reporting Problems

To display or collect general information about the ACE for use when reporting a problem, perform one of the following tasks:

Command

Purpose

show tech-support [details]

Displays general information about the ACE for use when you report a problem. You can use this command to collect a large amount of information about your ACE and provide the command output to technical support representatives.

This command displays the output of several show commands at once. The command output varies depending on your configuration.

The optional details keyword provides detailed information for each show command.

You can choose to have detailed information for each command or even specify the output for a particular interface or ACE. Each command output is separated by the line and the command that precedes the output.

The default output of the show tech-support command includes, for example, the output of the following commands:

When using this command, explicitly set the terminal length command to 0 (zero) to disable autoscrolling and enable manual scrolling. Use the show terminal command to view the configured terminal size. After obtaining the output of this command, reset your terminal length as required.

You can save the output of this command to a file by appending > filename to the show tech-support command (see Chapter 5, Managing the ACE Software). If you save this file, verify that you have sufficient space to do so; each file may take about 1.8 MB.

Redirects the same information as the show tech-support command output to a file on either the ACE disk0: or a remote server.

The keywords, arguments, and options are as follows:

•disk0:[path/]filename—Specifies that the file destination is the disk0: file system of the current context. If you do not provide the optional path, the ACE copies the file to the root directory on the disk0: file system.
